4 Claims.

My invention relates to building construction and particularlyjtoapressure relieving and wall strengthening joint. a

Among the objects, of my invention is to provide a pressure relievingand wall strengthening joint having a unitary structure therebyeliminating. the necessityof fillers; to create a joint formed ofasingle sheet of material, andhaving a plurality of integral raisedportions adapted to be forced down by excessive; weight to relievepressure; to supply a joint adapted to be folded on itself to produce awater tight course, and such other objects, advantages and capabilitiesas will later more fully appear and which are inherently possessed by myinvention.

While I have shown in the accompanying drawing preferred embodiments ofmy invention, yet I wish it understood that the same are susceptible ofmodification and change without departing from the spirit of myinvention.

Referring to the drawing, Fig. 1 is a plan view of one embodiment of mycompressible filler before it is bent for use; Fig. 2 is an enlargedsectional view of the form of my compressible filler shown in Fig. 1 andnow folded in use in building construction; Fig. 3 is a perspective viewof a different embodiment of my compressible filler partly unfolded.

The form of my compressible filler as shown in Figs. 1 and 2 comprises abody member ll adapted to be bent back on itself preferably at 22 toform an upper portion or layer l3 and a lower portion or layer l9; Aplurality of spaced raised portions 20 all preferably of substantiallythe same height are integral with lower layer 59. The upper layer 20 hasno raised portions and is uniformly level. When my compressible filleris bent back on itself at 22, the upper layer substantially covers andis superimposed over said lower layer thereby contacting the raisedportions of said lower layer. 7

The form of my compressible filler shown in Fig. 3 also comprises a bodymember ll having a central portion 29 having integral therewith aplurality of spaced raised portions 20. On either side of said centralportion 29 and integral therewith, is a level portion 28. Said bodymember I1 is adapted to be bent back on itself at both places indicatedat 32, the meeting places of the central with the level portion oneither side thereof, so that the level portions 28 substantially meet tosubstantially cover said central portion 29. When said level portions 28are superimposed over said central portion 29, said level portions 28contact said raised portions 20.

It is within the contemplation of my invention that in both forms thatthe structure may be reversed, so that the raised portions may beintegral withthe upper portion ill or portions 28 instead of the lowerportion 19 or central por- 5 tion 29 which, would in that case be level.

While I prefer to construct my joint or filler of ductile metal such aslead, or, fiber, rubber or the like, yet it is within the spirit of myinvention to construct my joint of any compressible mate- 10 rial havingsubstantially the same qualities as lead. My invention providing for ajoint of one piece of material eliminates the necessity of expensivefillers. By eliminating the need of any filler and making my joint ofone integral part, 15 I substantially decrease the cost and amount ofmaterial and labor.

While I have shown as illustrated in the drawing raised portions incircular form, yet I wish it understood that my raised portions may be20 in the shape of squares, triangles, rectangles, bumps or any otherform of raised portions without departing from the spirit of myinvention.

My joint may be used in any type of building construction andparticularly where the con- 25 struction is divided into zones. My jointmay be placed in any place and as many times as desired within each zoneand at any place between units of a wall.

The raised portions are of any desired height, generally of sufiicientthickness to create a joint of equal thickness to the mortar joint. Onepurpose of the fold is to produce a water-tight course. My joint comesin any desired width, and is delivered on the job out to fit the profile5 of each individual pier, thereby eliminating any additional expense insetting. My joint is of sufficient strength to carry the normal weightexpected to occur on the facing units.

In all buildings of stone, terra cotta, granite 4.0 or marble facadescertain destructive movements occur which cause the facing blocks tocrack or spall. These movements include: the compression of steel, theexpansion of stone due to temperature change, wind-stress, settlement,45 and vibration. These conditions are. frequently aggravated by faultysetting. To overcome any disastrous results from the above movements myjoint has been developed to incorporate a feature of elasticity into thewall which may not 50 be obtained as well in any other manner. When theexcessive weight is placed on the facing blocks there is relief providedsimply by the raised portions of my joint being forced down, whichautomatically restores the desired, intended 55 weight to the facingmaterial. With the use of my joint the building is zoned into storyheights. Where the stones are. bonded onto the floor or in the use ofshelf angles, this material permits these types of construction tofunction as intended by assuring, for the life of the building, that theweight of the facade will rest on either the angle iron or the floor.Another desirable feature of my invention is the elimination ofsubstantially all future tuckpointing.

My invention herein is new and differs, from my copending application ona patent for Building construction, Serial Number 91,520, filed July 20,1936 in that I have now provided that the raised portions on my jointare formed in only one of the upper or lower portions, whereas in mysaid previous application the raised portions occurred in both the upperand lower layers. With my new construction I eliminate the raisedportions on either the upper or lower layers thereby saving considerablyin expense, material and workmanship as well as saving the necessity ofconstructing the raised portions on boththe upper and lower layers sothat they may nest or meet. I also provide that the upper or lower layermay be in a pair of flaps instead of a centrally bent portion.

Having thus described my invention, I claim:

1. A unitary compressible filler for use as a pressure relieving jointin a wall structure comprising a sheet of material adapted to be bentupon itself to form an upper layer and a lower layer, only one of saidlayers having raised portions so that when said sheet is bent back uponitself one layer will contact the raised portions on the other layer.

2. A compressible filler for use as a pressure relieving joint in a Wallstructure comprising upper and lower metal members, one of said membershaving a plurality of raised portions, the other of said membersv havingno raised portions, so that when one of said members is positioned abovethe other of said members, the raised portions of one member willcontact the other member having no raised portions.

3 A compressible filler for use as a pressure relieving joint in a wallstructure comprising a sheet of metal folded to form upper and lowerlayers, and interposed spacing means comprising integral raised portionson only one of said layers.

4. A compressible filler for use as a pressure relieving joint in a wallstructure comprising a single pair of oppositely disposed metal members,only one of said members having raised portions, said portions adaptedto withstand a desired dead weight without substantial compression butadapted to be compressed by excessive pressure.
